Components of Blood • Whole blood • Red Blood Cells: Transport O2 to cells • White Blood Cells: Fight pathogens • Platelets: aid in clotting • Plasma • 90% water (solvent) • Solutes: Amino acids, glucose, hormones, vitamins, salts, waste, antibodies
ABO Blood Groups • Antigens: • Proteins that help identify cells as foreign or natural • Found on surface of RBCs • Help to determine your blood type • Analogy: Antigens are like jerseys • Antibodies: • Float freely in plasma • Attack anything with foreign antigens
What would happen if a virus with B antigens entered your blood? Your B antibodies will attack and kill this virus. Group A blood Vein • RBC’s have the A antigens on their surface • B antibodies in your plasma • only attack invaders with B antigens B antibody B antibody B antibody B antibody
Your B antibodies will attack, and cause clots to form. This person will die. What would happen if you gave this person type B blood? Group A blood Vein • RBC’s have the A antigens on their surface • B antibodies in your plasma • only attack invaders with B antigens B antibody B antibody B antibody B antibody
What would happen if a virus with A antigens invaded your blood? The A antibodies would attack and kill the virus. Group B blood Vein • RBC’s have B antigens on their surface • A antibodies in your plasma • only attack invaders with A antigens A antibody A antibody A antibody A antibody
Their A antibodies would attack the donated blood, causing blood clots. This person would die. What would happen if this person was given type A blood during a transfusion? Group B blood Vein A antibody • RBC’s have B antigens on their surface • A antibodies in your plasma • only attack invaders with A antigens A antibody A antibody A antibody
What would happen if this person was invaded by the viruses below? They do not have antibodies to attack these viruses. Group AB blood Vein • RBC’s have both A & B antigens on their surface • Neither A nor B antibodies in your plasma Can you predict the antibodies they will have?
